-- 8e04df6fcbd062e5eaf179a6ec9b0a26f8aa8a39 by Abseil Team <absl-team@google.com>: Use a floating point type for the example usage of absl::uniform_real_distribution. PiperOrigin-RevId: 271167776 -- 5f8f1dfea50bc16a9d9af3e50c4636500a938b29 by Abseil Team <absl-team@google.com>: the llvm wasm backend does not support this data symbol in text section, so remove it from the test. PiperOrigin-RevId: 271138100 -- 2874542cb212962ac3093fd78fd5e1eb85c126c0 by Xiaoyi Zhang <zhangxy@google.com>: Work around MSVC 2019 compiler bug related to constexpr in optional_test. The change in optional_test is necessary to avoid another bug on MSVC complaining about accessing invalid member of union, and also makes the test more reasonale by checking the value of a non-static member. Filed a bug against MSVC https://developercommunity.visualstudio.com/content/problem/743998/internal-compiler-error-related-to-constexpr-and-u.html. PiperOrigin-RevId: 271129805 -- 3a5d56f0c3362aabf68938fb95c4e2d3eca59538 by Abseil Team <absl-team@google.com>: Improve precision of absl::GetCurrentTimeNanos() by adjusting cycle time sooner. PiperOrigin-RevId: 271007945 -- 1e044a6dec7c0ca150fff1aee52dbdb16aa43ed7 by Abseil Team <absl-team@google.com>: Internal change.
